Abstract
Official abstract text for this publication.
An infusion pipe capable of achieving a flow rate higher or the same as that of a conventional product, and of easily joining to a cannula attached to an eyeball. The infusion pipe of the present invention is used in an ophthalmic operation with the infusion pipe joined to a cannula attached to an eyeball, and includes an insertion part to be inserted, at the time of joining to the cannula, inside a cannula piercing part, which is a part of the cannula for piercing the eyeball. A cross-section of the insertion part is an arc shape from which a part of a circle is cut out.
First claim
Opening claim text (preview).
The invention claimed is: 1. An infusion pipe used in an ophthalmic operation, comprising: an insertion part to be inserted inside a cannula joining part continuous with a cannula piercing part of a cannula for piercing an eyeball; a joining part having a diameter larger than a diameter of the insertion part, and configured to be crimped and secured by an inward protrusion formed in an inner surface of the cannula joining part of the cannula when the insertion part is inserted into the cannula; and a connecting part that connects the joining part and the insertion part, wherein the insertion part is shorter than the joining part, wherein a cross-section of the insertion part is an arc shape from which a part of a circle is cut out, wherein an arc height of the cross-section of the insertion part is 50% or greater and 70% or less of an outer diameter of a virtual circular cross-section that is intact, and wherein the infusion pipe is connected to a tube allowing perfusing water to pass therethrough.
